摘要
聚酯PET色值是下游用户关注的主要指标之一,准确测试PET切片色值对产品质量提升有着重要意义。本文通过研究仪器观察孔面积、样品前处理、检测环境等测试条件对PET聚酯色值测试的影响,为统一聚酯切片色值测试条件提供建议和支撑。
The color value of polyester PET is one of the main indicators that downstream users pay attention to.It is of great significance to accurately test the color value of PET slices to improve product quality.In this paper,by studying the influence of the instrument observation hole area,sample pretreatment,testing environment and other test conditions on the color value test of PET polyester,it provides suggestions and support for unifying the color value test conditions of polyester chips.
